P2453 on Land Rover
Diesel Particulate Filter Pressure Sensor "A" Circuit Range/Performance
P2453 on Land Rover vehicles indicates diesel particulate filter pressure sensor "a" circuit range/performance. Au7o has documented this code across 1 Land Rover model — most commonly on Defender. This code applies to diesel vehicles and means the engine computer detected that the diesel particulate filter (DPF) differential pressure sensor "A" signal is out of its expected range or behaving implausibly. This sensor monitors pressure across the DPF to track soot loading and trigger regeneration. An out-of-range reading means the computer can't reliably gauge how clogged the filter is, which can disrupt regeneration timing. It is generally not an immediate hazard, but if unresolved it can lead to DPF clogging and related emissions faults. Typical repair costs on Land Rover range from $300 to $1,600, depending on the specific model and root cause.
Common Causes of P2453
- •Faulty DPF differential pressure sensor
- •Clogged, kinked, or cracked sensor pressure hoses
- •Soot buildup blocking the sensor ports
- •Wiring or connector issues at the sensor
- •Actual DPF restriction skewing sensor readings
- •Moisture or contamination in the connector
P2453 on Land Rover by Model
Land Rover Defender(1 issue)
- DPF / EGR / VNT Turbo Carbon-Choke (2.2 EU5 Emissions Trio)2012-2016
The Euro 5 2.2 added a DPF, and the EGR/DPF/variable-vane turbo behave as one interlinked system that clogs with soot on short-trip, low-speed use. A carboned EGR dumps extra soot into the DPF, the DPF blocks and forces failed regens (diesel washes into the sump and the oil level rises), and carbon from the EGR/blow-by builds on the VNT turbo vanes so they stick and the engine drops into underboost/limp mode. The EGR cooler can also crack internally and let coolant into the exhaust circuit. This is the cluster of faults that puts a 2.2 into limp mode again and again.

What does P2453 mean on Land Rover?▼
P2453 stands for "Diesel Particulate Filter Pressure Sensor "A" Circuit Range/Performance." This code applies to diesel vehicles and means the engine computer detected that the diesel particulate filter (DPF) differential pressure sensor "A" signal is out of its expected range or behaving implausibly. This sensor monitors pressure across the DPF to track soot loading and trigger regeneration. An out-of-range reading means the computer can't reliably gauge how clogged the filter is, which can disrupt regeneration timing. It is generally not an immediate hazard, but if unresolved it can lead to DPF clogging and related emissions faults. On Land Rover specifically, this code is documented across 1 model.
What causes P2453 on Land Rover vehicles?▼
Common causes on Land Rover: Faulty DPF differential pressure sensor, Clogged, kinked, or cracked sensor pressure hoses, Soot buildup blocking the sensor ports, Wiring or connector issues at the sensor, Actual DPF restriction skewing sensor readings. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P2453 on a Land Rover?▼
Repair costs on Land Rover range from $300 to $1,600, depending on the specific model and root cause.
